1. The reporting persons are: (i) Steelhead Partners, LLC ("Steelhead"), a registered investment advisor within the meaning of Rule 16a-1(a)(1)(v) under the Securities Exchange Act of 1934; and (ii) each of James Michael Johnston and Brian Katz Klein, Steelhead's member-managers.

2. The issuer's securities reported on this Form 4 are beneficially held by Steelhead Navigator Master, L.P. ("Steelhead Navigator"). Steelhead is the investment manager of Steelhead Navigator. As a greater than 10% beneficial owner, Steelhead Navigator is separately reporting its holdings in the issuer's securities on a Form 4 filed concurrently herewith. Each of Steelhead, Mr. Johnston, Mr. Klein and Steelhead Navigator expressly disclaims beneficial ownership in these securities, except to the extent of their respective pecuniary interests therein.

3. Steelhead and the other reporting persons may be deemed to beneficially own the securities owned by Steelhead Navigator insofar as they may be deemed to have the power to direct the voting or disposition of such securities. The reporting persons have elected therefore to file this Form 4 voluntarily to report Steelhead Navigator's holdings, notwithstanding the reporting exemption applicable to registered investment advisors under Rule 16a-1(a)(1)(v) and to control persons under Rule 16a-1(a)(1)(vii). The filing of this Form 4 should not, however, be deemed an admission by any of the reporting persons that such person falls outside the scope of the foregoing exemptions, or that the reporting persons and/or Steelhead Navigator form a group within the meaning of Rule 16a-1(a)(1).

4. Consistent with the position taken by the issuer in its Schedule 14A filed with the Securities and Exchange Commission on April 29, 2011, 4,024,005 shares of the issuer's Class A common stock (the "Convertible Note Shares") that may be issued to Steelhead Navigator upon the conversion of certain convertible notes held by Steelhead Navigator (the "Convertible Notes") are not included in this Form 4 because the receipt of such Convertible Note Shares is contingent upon the issuer's determination, in its sole discretion, to deliver the Convertible Note Shares instead of cash upon conversion of the Convertible Notes.
